عنوان انگلیسی The State of Peripheral Blood Natural Killer Cells and Cytotoxicity in Women with Recurrent Pregnancy Loss and Unexplained Infertility
چکیده انگلیسی مقاله Objective: : The prognostic value of peripheral natural killer (pNK) cells, as a screening test in women with recurrent pregnancy loss (RPL) and unexplained infertility is still a matter for discussion. The aim of this study was to compare the percentage of circulating CD56+NK cells, CD69 and perforin markers between women with unexplained infertility and RPL with healthy control group. Materials and methods: In this case control study, the percentage of CD56+NK cells and activation markers (CD69 and perforin levels) in the peripheral blood were measured in 25 women with unexplained infertility, 24 women with idiopathic RPL and 26 women from the healthy control group, using specific monoclonal antibodies by flow cytometry. Results: The percentage of CD56+NK cells was significantly higher in patients with infertility in comparison with the healthy control group (P=0.007). There were not significant differences either in the total number of CD56+ cells between the RPL group and the control group (p=0.2) or between the RPL group and the infertile group (p=0.36). The percentage of CD69+ lymphocytes in RPL group was significantly higher than in the infertility group (p=0.004). There was statistically significant difference in Perforin levels between RLP and control (P=0.001) as well as RPL and infertile (P=0.002) and the three groups. Conclusion: An increased percentage of CD56+NK cells in patients with unexplained infertility, an elevated expression of CD69 on NK cells in patients with RPL and infertility and a high level of perforin on CD56+ cells in the RPL group might be considered as immunological risk factors in these women.
